The clear reason the driver was killed is due to the lack of lower bumper on the trailer to stop a car from continuing to the last axle of the trailer of the truck.

Maybe BMW can use this to influence a change in safety requirements, and make it illegal to have unsafe trailers on the roads without proper bumpers to prevent this kind of tragedy in the first place.

This was not a high speed test, this is what happens without proper lower bumpers in place.

Very very sad.

It's the awful events and devastating, almost explicit pictures like this that hit home the reality of danger on the road and encourage change, in pursuit of advanced safety. A sole vehicle can only do so much and I agree that bumper height and design legislations need to be changed on trucks.
My condolences also go out to family and friends of this man, and to his colleagues at BMW, but hopefully some good can come out of this and more lives can be saved.
